Methods of Establishing Intersegmental Plane in Segmentectomy

After the identification the targeted segmental bronchus during the operation,ligating the proximal end of the targeted bronchus. Put the vessel separation forceps in the distal bronchial space to avoid the accidental damage of the vessels. Use a 50ml syringe to inject air into the distal bronchus (about 100ml is expected) until the intersegmental plane is satisfactory. Divide the target bronchus using the cutting and closing device.

Divide the target bronchus using the cutting and closing device. Ask the anesthesiologist to inflate the lung completely from pure oxygen to the affected side and then change to single lung ventilation. Wait for the intersegmental plane to appear(usually about 15 minutes).
